LCC compiler for Elbrus is not a ported GCC, though ported GCC also exists. LCC looks like GCC for user to simplify migration from other ISA's with GCC, but it has own optimizer and own codegen. It even doesn't support GCC frontends except gfortran (which was specially ported for LCC), and it uses EDG and clang frontends for C, C++.
